dead link to External Resources for libjava3d-java

[Martin Johannes Dauser <mdauser@cosy.sbg.ac.at>]

Hi,

on
https://packages.debian.org/source/wheezy/java3d
and the linked pages
https://packages.debian.org/wheezy/libjava3d-java
https://packages.debian.org/wheezy/libjava3d-java-doc
https://packages.debian.org/wheezy/libjava3d-jni

the link for External Resources leads to a not existing 
"java3d.dev.java.net". I think it should be https://java3d.java.net/ .

Best regards
Martin Dauser
